in general no, but it depends where you apply
25-26 is comfortably above average (80-85%, I believe), meaning that in general, yes
! The "it depends where you apply" part is true, though, and key. Whether a score is good *enough*, on its own, to put or keep you in the running for acceptance to a particular school...that's another question altogether, and that would be true whether you'd gotten a 20 or a 30, as well. Whether it's good relative to your PSAT/SAT scores, whether it's good relative to your past performance on standardized tests...all different (and valuable) questions.
You should be able to find average ACT scores of admitted students via schools' webpages, USNews, Princeton Review, random other college info sites, etc.
Best of luck
